SimpleUserFolder and sha-crypted passwd
by Bjørge Solli 15 Jan '03

15 Jan '03

Hi I want to put my old loginmanager to rest and put something simple in. SimpleUserFolder sounds nice, but it seems to do the password matching itself, and since I have sha-crypted passwords, I need to match the passwords in encrypted format. Any ideas? If none, can u please tell me to *not* use SimpleUserFolder(perhaps you have an alternative as well?). For the record; I keep my users in a database.

tales expressions issue
by David Bear 09 Jan '03

09 Jan '03

I have a formulator form with 12 form objects -- some text boxes, some check boxes, etc. There are 3 multicheckbox objects that want to populate with objects from a folder object. Ergo, I have a multicheckbox objects called department, population, and institution. I also have folder objects by the SAME name at the same level in the zope heirarchy as the formulator form. I have a python script called listTitles also. Now the strange thing happens when I use a python expression in to populate each of the above mention checkbox fields. I use "python:form.department.listTitles()" to populatre the department formulator object. It works. I use "python:form.population()" to populate the populatio formulator object -- it does NOT work. Same thing for institution. I'm begining to wonder if I can only have one expression on a formulator form. Any idea's what might be happening? I can put in the url "http://server/test/department/listTitles" and I get back a python list of objects in the department folder. Which is what I expect. (so I know acquisition is working as I think it should) -- David Bear College of Public Programs/ASU Mail Code 0803

CMFCore.DirectoryView
by Elena Schulz 06 Jan '03

06 Jan '03

Hi, I try to connect ZPT to my local Filesytem. Previouesly I used localFS and DTML which worked nicely. But according to an earlier post by Dieter I learned that I should use DirectoryView from the CMFCore now. But thats not so easy as I found. Does the registration have to be done on every serverstart again? (How to automate it if so?) How to add new extensions and metatypes? Up to now I succeeded to register an arbitrary Directory on my local FS and different MetaTypes with the external Method given below. But a corresponding klass has to be given for the registration. How to do that using classes like the 'FSObject' return bad file error when I try to view the object in ZMI. Does anybody know about that? (Or how to use local FS under ZPT?) -- many thanks for your replies, Elena the code: from Products.CMFCore import FSObject from Products.CMFCore import DirectoryView DV=DirectoryView def registerLocalDir (my_dir='my_absolute_FS_path', prefix="", extList=['css', 'js'], metaList=['Style Sheet'], subdirs=0): DV.registerDirectory(my_dir, prefix, subdirs) klass=FSObject for ext in extList: DV.registerFileExtension(ext, klass) for mt in metaList: DV.registerMetaType(mt, klass) return

The installation went without incident, but when I try to view a Photo/PhotoFolder, I get the error message" Error Type: NameError Error Value: global name 'PIL' is not defined I've read what I can on the web and in the docs, and it seems that the Python version running Zope can't access PIL.

Howto use getattr() without acquisition?
by dave＠loewen.com 01 Jan '03

01 Jan '03

I'm building a python script to generate breadcrumb navigation links on each page of my website. It creates hyperlinks and uses the title or id for the link. I'd like to add a feature so that if the folder has a "nickname" property, it will use this for the breadcrumb hyperlink instead of the title. I tried using "hasattr()" to see if the current folder has a nickname property. It seems to work if the folder has a nickname property. However, if the folder doesn't have that properly, but the parent does, it still returns "true" and then getattr() acquires it from the parent instead of using the title. Is there a way to tell hasattr() to *not* use acquisition? Or perhaps another method which would do what I want? I'm sure there is a much more elegant way to do this... (These question feels like a FAQ, and I did do my best to search the group archives, but couldn't find anything appropriate-- most breadcrumb conversations seem to revolve around DTML and getProperty().) --dave """ This script creates breadcrumb style navigation links. It walks the REQUEST.PARENTS list of parents and creates a hyperlink for each parent. It stops at the Examples folder. """ links=[] for parent in context.REQUEST.PARENTS[1:]: id = parent.getId() if hasattr(parent, 'nickname'): label = getattr(parent, 'nickname') elif parent.title != "": label = parent.title else: label = parent.getId() links.insert(0, """<a href="%s" class="breadcrumb">%s</a>""" % (parent.absolute_url(), label)) # Now get label for current container if context.hasProperty('nickname'): label = context.nickname elif context.title != "": label = context.title else: label = context.getId() return " : ".join(links) + " : " + label

PUT_factory -- Script Import Permissions
by Matt Young 01 Jan '03

01 Jan '03

Hi, I need to write a PUT_factory so that FTP and WebDAV uploads create the right type of objects in Zope (by default everything is mapped to three objects but you can override this). The PUT_factory needs to be a script so that I can place it in the affected directory (I want to override the default for a "file share" directory), and because I can't write external methods on this account. Once the factory determines the type of object to be created, it needs to return an empty object of that type (for instance, a File or ExtFile). Problem is, a script can't import the definition of File etc., so I can't invoke its constructor. DOES ANYONE KNOW HOW I CAN CREATE A File, ExtFile, ETC. FROM WITHIN A SCRIPT AND RETURN IT (EMPTY) AT THE END OF THE SCRIPT? Please note that using manage_ functions probably (?) isn't the right way to do this.

Creating Page Templates using XML-RPC
by Gordon Lai 01 Jan '03

01 Jan '03

Hi, I'm assisting another programmer who's using Zope to create a new version of our website. I need to create about 3000 relatively static pages (the actual content is static, at least for a few months, until the next time I update the pages; the content is surrounded by a header, a footer, and a sidebar which may change depending upon news announcements). I'm new to Zope and just want to create the pages and then get out of the other programmer's way. For our old site I wrote a Python script that creates these 3000 pages and use SSIs to pull in a header and footer. I can do the same thing for the new site by using macros to pull in Zope page elements. However, I'm a bit confused as to how to do this. My questions: * In looking through our site using the Zope manage interface, it seems as though every page is represented by a Page Template. Is this true? Do I need to create 3000 Page Templates? * If the previous is true, how do I create Page Templates programmatically? It seems XML-RPC can work for me, but I can't find an API to create Templates. Does one exist, or should I be using a different method? Thanks for any assistance, GL __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

Are Lookups via DTML methods efficient?
by Jonathan Mark 01 Jan '03

01 Jan '03

I have a list of easy-to-remember website names, and hard-to-remember URLs. My goal is that when coding my Zope site using DTML I should be able to refer to a URL by its easy-to-remember website name. I am thinking of creating a near-identical group of DTML methods whose IDs are the website names and whose titles are the URLs. Each method would then return its own title. Is this approach efficient? I could call a SQL database instead, but I think that would be overkill in this case. Also, opening up a connection for this simple information might not be efficient either. Should I use a field index on a catalogue instead? Each website name would only have a single URL, so the search would only return a single value. Could there be an XML approach which might work well? Ultimately I could have hundreds of URLs that I want to call by website name. __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.
